IT also looks like the Aristo harness has 2 yellow plugs and one grey square plug where the Supra has 3 yellow plugs that goto ECU and an Orange plug that goes to a sub ECU of some sort.

Looking through this thread I see a lot of concerns about wiring. I just wanted to let everyone know that if you want to do the swap and keep the Aristo ECU and harness, I can rewire it to plug and play into the Supra (or whatever car you're swapping it into). Or, for example, you want to run an AEM on an Aristo harness, I can rewire it to work. I specialize in Toyota wiring conversions.

i have problems with the fuel line. i bought a USDM 95 TT motor and swaping into a 98 VVTI NA. the guy at the shop is having trouble with the fuel line, he say its too short or something like that. he ordered the parts from a toyota dealer, any of you guys might know what to do in my situation ? should i custom made the fuel line ?
If you're looking for a simple, inexpensive fix, then you can go down to your local parts store and look in the "HELP!" section for an EFI hose connector (it looks like a double-sided brass hose barb). Then pick up a back of EFI clamps (they are like mini t-bolt clamps) and cut each of your fuel lines, then connect them together with the connector and clamps.Originally Posted by 2JZ_WHAT
Or, you can look around for a Toyota fuel line that is long enough, or just go custom-made.

I dont mind paying more rather than doing something that i will regret or it will cause more damage in the long run. Thanks for the help. i'll update once i had it done.
Redline are red and Turbos are blue.
Nothing is sweeter when i drove past you.
If im buying a jdm 2jzgte off a supra not aristro with an automatick jdm ecu i can run the jdm auto ecu even though im using my na 5spd right? Also if i get it with the engine harness with it will it still work using my tranny? The reason why im asking is because the 2jzgte im going to buy comes with the auto tranny which im not going to use but also comes with ecu and wiring harness.....
Retarded question but I must know.
If i do a full JDM Supra (non-aristo) swap, will i need to install a BCC? or does it only apply for the USDM supras?
Can't remember but somewhere I heard a guy did a 100% jdm swap and all he did was hook up the boost controller and took it from there, not totally sure though...
Oh what the hell i'll know a few questions out of the way-
I am swapping the NA auto to JDM Supra TT auto. What do I need to replace? I hope it's only the driveshaft, but will anything else be required? Can I still use my NA tranny mounts?
JDM Supra TT package (ecu, tranny harness will be extended) and my parts list so far is:
-TT FUEL PUMP + 12v mod
-MODIFIED DP FOR JDM TURBOS
-TT Tranny drive shaft
-TT tach
-TT/TRD mounts
-Passenger's side engine mount bracket for an OBDI Supra
-SMIC w/ piping
-Possibly TT intake pipe
-Koyo radiator w/ pipes
-e-fans
Plus any other maintenance parts/fluids. Sound good? or what else do I need to add
Thanks.

Correct me if Im wrong but, a JDM ECU (which more than likely came from an Automatic Supra) Should by default start up a JDM TT (440cc) motor once I get the wiring all setup.
The automatic part should not matter as that assists the Automatic tranny with shift points. If I am manual, that compatibility is not needed as you make your own shift point.
I assume all I will need is the TT Throttle body Cable, and a GS400 Power Steering Resevoir
I got a 95 Supra SE with an AT and GE motor. I was looking at what I needed to get to switch over to a TT engine, (is it even possible?). Any suggestions?
I've seen a few stock tt engines go for around 2900 to 3500. I assume it couldnt be that much more money if you were to get a getrag v160 tranny no? Right now i'm still planning everything out.. gonna be lookin for an NA hardtop soon and want to do the stock tt conversion on it and eventually run a single turbo. all in time
IMO to get your hands on a getrag its like getting your hands on gold.. if u buy one new from the dealer your looking at 5700 (last i checked), for a used one probably around 3000 or so
OK I created an Excel Pinout map that outlines the wiring changes needed. to match a GTE harness to my GE AEM EMS. it seems only a few items need to be addressed as I dont need A/T tranny wiring or cali emissions wiring
ok look in the long run your just going to spend more money and have more head aches than neccessary heres what i did
jdm aristo motor 2500$
u.s spec wiring harrness 700$
u.s spec ecu 200$
ebay intercooler and piping 485$
ebay exhaust and down pipe 300$
used u.s spec injectors 60$
still watching you guys trying to figure out your jdm harrness with your usless diagrams .........priceless for every thing else theres a smart ass 18 year old kid laughing at you cheap old foggies.....lol
me and my buddie both did the swap and i finished in 3 days his took him over 2 months trying to figure out diagrams and buy missilanious stuff that wasnt neccessary. my car has ran fine ever since and he is still trying to work out the bugs in his. i dont care what any body says everything is plug and play why in the hell should i pay some one 2000 dollars to put 2 conectors together when i could do it my self for free thats like paying someone 20 bucks to plug in your vacume every time u use it.
my point is just do it right and dont try and half ass it. cause in the end you just get half ass results
Well,
I for one do all of my own work, I dont poay anyone to do anything for me, unless its special fabrication that is needed for whatever reason.
I too purchased:
Aristo GTE $1700 (did a complete teardown and rebuild on it)
USDM TT/6spd Wiring Harness (used) - $200
AEM EMS (#1101 NA/SC300)
JDM TT Supra ECU - (came with Swap)
ebay intercooler and piping $400
Boost Logic piping and single conversion parts.
440cc JDM Stock injectors (using it until I upgrade to a bigger rail over summer)
I just like to pre plan things so when I devote my time to the project it is not standing there and scratching my head. I like to make the most out of my time.
My motor should be going in very soon. I have the engine wired up already.
looks great altezza, glad people are finally tackling these swaps themselves, i did my own in m back yard, it wasnt that hard to tell you the truth, as long as you have the tools, patients, and the repair manuals and your good to go! best of luck keap us posted

Thanks, Im just doing a little detail work as i go along so I dont have to stress myself out when the motor is in the car. Im neatening up/eliminating all the extra coolant and vacuum lines before it goes in.
i hear you man, i took my time on mine, i also ran the 440 injectors, stock jdm twins, and the stock jdm ecu and everything that came with it, it works fine, i got 1 code but that was my o2 sensor, never had a problem though, best of luck, let me know if you have any questions you know how to IM me
Ben Y
For certain. Im just doing a little travel for business nwo so I dont have as much spare time, but i hope to have this swap running before end of May.
Ive got a jdm 2jzgte going into a 1994 na mkiv.
The only thing that really concerns me is the dash questions......anyone have a write up on how to rewire? pardon my ignorence but what exactly wat part do you mean by twin turbo tach?
And by the way ive been told you need a tt auto diff......think turbo aristo ones work as well. The soarer ones might but im not to sure.
By the way im in need of a complete jdm engine loom.
loom as in harness? is so and u plan on working this motor imo u should get a us harness and us ecu rather then the jdm ecu and harness
Yup loom as in Engine harness...my bad
Ive got a jap na and 2jzgte supra engine. So i think id need a jap Engine harness.
So who has acutally done this swap!
I just have some simple questions that i cant get a proper answer to.
If going from auto na to tt auto do you need a tt auto d/shaft?
Is the diff in a tt auto the same as a na auto?
And does anyone have a jdm 2jzgte supra loom for sale?
cheers
after 4 pages, is there even just a list? I know we need to do this for my friends swap, PLEASE tell me what might also be needed?
USDM 550cc injectors
MAF sensor
USDM ECU
USDM wiring harness
USDM cams
TT radiator
USDM fuel pump
USDM oil pick up
USDM oil pan
TT driveshaft
What else? We are wanting to make it plug N play! Any other sensors? We want to do it right the first time.
Its an NA automatic 1995 SE model, we just need to throw his motor thats been sitting all year!

I was comparing the GTE wiring harness to my current NA harness and engine bay and I noticed that one of the plugs going into the Relay Box behind the battery is different.
I confirmed in the Manual that the NA-GE motor has a 3 pin plug named EA3 (pg EG-658 of manual vol1) and the TT-GTE motor harness has a 5 pin plug of which four are used named EA2 (pg EG-811 vol1)
It looks like there is a second red/black wire on the GTE. I was wondering how did you all overcome this Connector Mismatch?
(according the the schematics int he manual - it looks like those Black/red wires on EA2 and EA3 feed the O2 sensors?) Can anyone confirm?
There is also another 8 pin grey plug right next to the Ignitor and resistor box setup. plug # 10897. What exactly does that plug into. it seems like it should connect to something on the driver shock tower, but nothing is in the vicinity.
Does the TT ignitor mount in the same place as the GE ignitor?
